The random floor is a nice solution to bring randomness to a 2d platformer. I'm also a fan of the health system. I just wish there was a bit more feedback with particles and sound that you really know: YOu got hit! You know?
Yes the feedback is too little for now. For example, there's only one SFX, which will be played when brouncing happens. In the future I will add more feedback to the game.
